Abstract
(EN)
Disclosed are an electronic device, a packet transmission device, and a method for same according to an embodiment of the present invention. The electronic device includes: a communication unit which transmits a signal; and a processor which encodes source data at a predetermined bit rate, generates a data packet and a parity packet for restoring the data packet, and controls the communication unit so as to transmit the signal including the generated data packet and parity packet, wherein the processor identifies the available bandwidth of a channel on which the signal is transmitted, and controls the communication unit to transmit the signal with a portion of the data packet or the parity packet included in the signal excluded when the identified available bandwidth is smaller than the bit rate. According to the present invention, the quality of a communication service may be enhanced by adaptively excluding packets according to the real-time wireless channel environment.

La présente invention concerne, selon un mode de réalisation, un dispositif électronique, un dispositif de transmission de paquets et un procédé pour celui-ci. Le dispositif électronique comprend: une unité de communication qui émet un signal; et un processeur qui code des données source à un débit binaire prédéterminé, génère un paquet de données et un paquet de parité destiné à rétablir le paquet de données, et commande l'unité de communication de façon à émettre le signal incluant le paquet de données et le paquet de parité générés, le processeur identifiant la largeur de bande disponible d'un canal sur lequel le signal est émis, et commandant l'unité de communication de façon à émettre le signal d'où une partie du paquet de données ou du paquet de parité comprise dans le signal est exclue lorsque la largeur de bande disponible identifiée est inférieure au débit binaire. Selon la présente invention, la qualité d'un service de communication peut être renforcée en excluant de manière adaptative des paquets en fonction de l'environnement de canal sans fil en temps réel.
